Definitions

  • the present invention finds advantageous applications in the field of the automotive sector. It relates to a micro-hybrid device in a motor vehicle.
  • This micro-hybrid device aims on the one hand to recover electrical energy during braking steps and, secondly, it aims to restore this energy according to the consumption of various electrical and electronic equipment that includes the motor vehicle.
  • the regenerative braking device is connected to a vehicle electrical distribution network that includes a battery for storing this converted electrical energy.
  • This battery is usually a conventional lead battery.
  • the electrical distribution network restores the energy stored in the battery to the various electrical and electronic equipment embedded in the motor vehicle.
  • the architecture of all the components belonging to the electrical distribution network, or network of the vehicle, is that of a cascade connection, also referred to serial connection thereafter in the description.
  • a problem with this type of architecture is that with a single battery on the distribution network, it is fast discharged when all electrical and electronic equipment consumes at the same time. This disadvantage is all the more penalizing as these equipment consume a lot of electrical energy.
  • a typical solution to this problem is to increase the storage capacity of the battery.
  • the physical size of such a battery then becomes very important.
  • This solution has various disadvantages, especially the price because such a battery is relatively expensive, and their mounting increases the size of the entire engine compartment of the vehicle.
  • the arrangement of such a battery in an inaccessible environment goes against the problems of handling, weight, robustness and cost.
  • the energy batteries currently used are conventional batteries. These batteries are not adapted to be charged with large currents for a sufficient time to ensure recovery of energy from the braking device. With this type of device, the management of this transient energy is not very effective for regulating the voltage flowing in the electrical distribution network of the vehicle.
  • Another solution is to equip the power system of the vehicle with a second power distribution network with a secondary energy storage having a storage capacity different from that of the main battery or main storage.
  • the second distribution network coexists with the first network having the main storeroom.
  • the second network having the secondary storer delivers a floating continuous supply voltage and the first network having the main storer provides a low DC supply voltage, generally less than said floating voltage.
  • a global bi-voltage network for the distribution of electrical energy is thus obtained.
  • the two storages are coupled to each other via a reversible DC / DC voltage converter.
  • the converter has the function of allowing energy transfers between the two storage facilities and the distribution networks.
  • An electric power generator comprising an alternator or alternator-starter coupled to the engine of the vehicle, directly supplies electrical energy to the secondary storer and, through the converter, the main storer.
  • the super-capacitor Compared to a conventional lead-acid battery, the super-capacitor is indifferent to the number of charge / discharge cycles and their depth and is little constrained at the level of the charge voltage which can vary in large proportions.
  • This type of dual-voltage power supply system is also in the form of a series architecture.
  • the two storages used in such a system can better meet the problem of energy supply of the vehicle.
  • a dual-voltage type architecture integrates with difficulty in the vehicle, due to a relatively complex connections and bulky components to implement under the hood of the vehicle.
  • the patent application DE10042414 (A1 ) describes a device according to the preamble of claim 1.
  • the system also includes a battery and the assembly of these system components is performed according to the parallel architecture.
  • the charge of the super-capacity from the battery and the return of the energy stored in the super-capacity to the battery are made according to the state of charge of the super-capacity and at least one parameter feature representing an existing power availability or a request for an electrical machine present in the system.
  • the object of the present invention is to provide a parallel-type micro-hybrid device allowing a better exploitation of the performances of the batteries compared to the solutions of the prior art.
  • the device comprises, in a cascade electrical connection, a rotating electrical machine mechanically coupled to a vehicle engine, an AC / DC converter, a DC power supply bus, the power supply bus dc power supply being connected to the AC-DC converter and being connectable to the terminals of an energy storage battery supplying a vehicle electrical distribution network, and high capacity energy storage means which are mounted in parallel with said cascade connection through a reversible DC-DC converter connected to the DC power supply bus.
  • the device also comprises electronic control means as defined in claim 1 appended hereto.
  • the figure 1 shows a schematic representation of a device 1 for recovery and return of electrical energy installed in a motor vehicle.
  • the figure 1 shows a voltage generator / electric motor 7 connected to a DC bus 3.
  • the voltage generator / electric motor 7 comprises a polyphase electrical rotating machine 4 mechanically coupled to a heat engine of the vehicle, more precisely to the crankshaft of the heat engine, and a AC / DC voltage converter 2.
  • the AC / DC converter 2 is an electrical device allowing to convert a DC voltage into several AC voltages, one per phase.
  • the AC / DC converter 2 has a plurality of bridge arms (not shown). Each bridge arm has several electronically controlled switches.
  • the AC / DC converter 2 is a three-phase inverter-rectifier driving the rotary machine 4 in electric motor mode.
  • the DC bus 3 comprises a DC voltage source 5.
  • This voltage source 5 is in a preferred example a battery or a rectified network.
  • the concept of battery is understood in the present invention as covering any device forming a rechargeable electric energy reservoir, at the terminals of which a non-zero DC voltage is available, at least in a non-zero load state of the device.
  • This voltage source 5 is supplied by the electrical machine 4 via the AC / DC converter 2.
  • the DC bus 3 comprises electrical or electronic equipment 6.
  • This equipment 6 includes connection lines connected in series to the voltage source 5 or electrical consumers connected in parallel to the voltage source 5.
  • the electrical consumers in a motor vehicle can be, among other things, headlights, a radio , air conditioning, ice towels, etc ....
  • the electric machine 4 may be an induction motor or a synchronous machine.
  • the equipment 7 combining the electric machine 4 and the AC / DC converter 2 may be an alternator or an alternator-starter.
  • the reversible starter-starter concept is a conventional alternator that offers the ability to start the heat engine in converter mode and a high-efficiency current generation in rectifier mode.
  • alternator mode the alternator-starter generates an electric power 15% higher than that obtained via a conventional alternator.
  • reversible mode it allows a fast and quiet start of the motor fully managed by electronics.
  • the alternator-starter is easy to implanted. It is compatible with current vehicle architectures and power networks.
  • the device for recovering and restoring electrical energy 1 is connected in parallel to the DC bus 3, at the terminals of the battery 5. It can be connected in a simple manner to any type of equipment 7 of a motor vehicle. Because of its parallel connection, this device 1 does not need any adaptation system when it is connected to the conventional dashboard of a motor vehicle.
  • the device 1 can be integrated in different places of the motor vehicle, even elsewhere than under the hood.
  • the integration of the device 1 in a motor vehicle is flexible. This flexibility of integration makes it possible to reduce the constraints of implantation on the vehicle.

  • the AC / DC converter 2 and the electrical machine 4 are close and the battery is conventionally under the hood.
  • the device 1 of the invention solves these problems of the state of the art by its flexibility of integration into the motor vehicle. It is thus independent of the various elements of the motor vehicle.
  • the device 1 of the invention optimizes the efficiency of the engine of the motor vehicle. It thus makes it possible to store energy in an energy reservoir 9 when it is surplus, in the braking phases for example, and to restore it when possible, especially in the phases acceleration, starting, when the heat engine is stopped to feed the DC bus 3 or alternator phases, engine running, to relieve the alternator and thus reduce fuel consumption.
  • the micro-hybrid device comprises in the case described a DC-DC converter 8.
  • the converter 8 converts the power delivered by the alternator under a constant voltage into the same power under a variable voltage of 0 to 60 Volts for example.
  • the DC-DC converter considered may have a parallel chopped topology. In this case, it provides an output voltage greater than the input voltage. It is understood that the DC-DC converter can respond to other topologies such as, for example, serial chopper or inductive storage. In a serial chopper, the converter supplies an output voltage lower than the input voltage.
  • the converter of the invention is sized according to the braking power to recover.
  • the converter 8 is a switching converter capable of absorbing voltage ripples in alternator mode, since its switching frequency and its bandwidth are much faster than the ripples of the voltage at the terminals of the DC bus 3.
  • the device 1 therefore comprises the energy reservoir 9 connected to the converter 8.
  • the energy reservoir 9 is preferably a super-capacitor.
  • the energy reservoir 9 may be any other type of energy reservoir for carrying out the invention. It is chosen for a voltage higher than 12 volts. It can advantageously admit up to 60 volts for low voltage networks and a few hundred volts on hybrid vehicle networks.
  • this energy reservoir 9 is a capacitor of large capacity more commonly known as designation EDLC.
  • This energy reservoir 9 is loaded during braking. It can be charged at voltages greater than 12 volts.
  • This type of large capacity energy tank can be charged with large currents for a short time. For example, for five seconds, this type of energy reservoir 9 can allow energy storage with powers of several kilowatts, that do not allow conventional batteries. Conventional batteries do not allow to accept such a large instantaneous power.
  • the physical size of the energy reservoir 9 can be reduced by 20 to 30% compared to the conventional size of the supercapacitors used in a series architecture.
  • the micro-hybrid device as described makes it possible to recover the electrical energy coming from the equipment 7, the converter 8 performs the adaptation of the voltages between the equipment 7 and the energy container 9. This electrical energy is then stored in the energy tank 9.
